CUTTER ATTACHMENT.

Application filed .Tune 4,

To all whom t 'may concern Be it known that I, JOHAN ENHOLDT, a citizenof the United States, residing at Chicago, in the county of Cook andState of Illinois, have invented certain new anduseful Improvements inCutter Attachments, of which the following is a speciication.

rThis invention relates to improvements in cutter attachmentparticularly adapted, though not necessarily limited in its us withpaper hangers cutters.

Heretofore in paper hanging and especially when fabric is placed uponthe walls considerable difficulty and inconvenience is experienced incutting off the overlapping portions of adjacent strips of material sothat the adjacent ends will abut and lie smooth and flat upon the wall.At present this is generallyT done by means of a knife and the use of astraight edge along which the knife is drawn, while the fabric restsflat aeainst the wall. This operation is not entirebly satisfactorybecause in order, to make a clean cut the edge of the knife cuts intothe plaster of the wall which dulls the knife. Furthermore, as thefabric has'paste applied to thefback thereof it is more or less n moistand only a very small amount of the fabric can be cut at one time as theedge ofv close proximity with the edge of the cutter so'that the fabricwill be readily cut by drawing the cutter therealong, and the surface ofthe wall will not be injured or marred either by the attachment or thecutting edge of the cutter.

A further object is to provide lan improved attachment of this characterembodying a shoe like portion which extends over and co-operates withthe cutting edge of the cutter and which attachment is adapted to beturned back or out of the way,pwithout detaching the same from thecutter, so as' to expose the cutting edge of the cutter for' sharpeningor other purposes.

A further object is to provide an improved device of this characterwhich will be sirn` 1923. Serial No. 643,215.

ple7 durable, cheap, light andcompaot in n `of thek several partshereinafter more fully described and claimed and shown in theaccompanying drawing illustrating this invention,l and in which-f Figure1 is a View in side elevation of a cutter having an attachmentconstructed in accordance with the principles of this invention appliedthereto.

Figure 2 is a detail sectional view taken lon line 2 2, Figure/1.

Figure 3 is a view similar to Figure 2, with parts omitted.

Figure 4 is av vertical sectional view taken on line 74%, Figure 1.

Figure 5 is a detail'perspective view of the attachment detached fromthe cutter and withv parts broken away.

Throughout the specification and lclaims` the term shoe like member willbe applied to one of the parts for describing the same,

but it is to be understood that this term is not to be considered asaterm of limitation v Vber which is suitable for the purpose.

Referring more particularly to the drawing the vnumeral 10 designates acutter having a handle l1 applied thereto and which, in the presentinstance, illustrates a cutter or knife which is usually employed bypaper hangers and commonly known as apaper hangers knife. It is to beunderstood, howf ever, that thisattachment maybe applied to any otherform of knife. f-

The numeral l2 designates a substantially U shaped member of` anydesired size and configuration and constructed of any suitable materialbutrpreferably of a resilient material such as metal or the like. tionof the member l2 is cut away as at 13 to provide a depending portion letarranged preferably at substantially right 'angles' to the portion 12.

A shoe like member l5 also constructed of any suitable material, butpreferably metal, is pivotally connected at one end as at 16.

A porwith the portion 14 so that the member 15 will be adapted for freepivotal movement about the pivot 16 to be moved into and out of positionand substantially parallel with the member 12.

The shoe like portion 15 is provided with an opening 17 preferablythrough the bottom thereof and at a point preferably spaced from theextremity 18. A deflector 19 is arranged adjacent the opening 17 so asto detiect particles of the material being cut by the cutter and also toform a discharge outlet for any paste which may be carried by thematerial into the shoe like portion or between the shoe like portion andthe edge of the cutter 10.

rllhis opening 17 may be of any desired size and the deflector 19 ispreferably formed from a portion of the bottom of the member 15 anddeflecting the same upwardly and into the shoe like portion 15.

Any suitable means may be provided for yieldingly restraining the member15 from movement about its pivot 16 with respect to the member 12. Tothat end a yportion of the member 12 may be cut and shaped to form apair of co-operating spring like jaws 20' opening downwardly and in adirection towards the member 15. The member 15 is provided with aportion 21 adapted to pass between the spring like jaws 2O to beyieldingly held thereby and thereby hold the member 15 in an operativeposition.

rlhe jaws 2O and the portion 21 may be r of any desired configuration.

The member 15 is also preferably provided with an upwardly projectingbeveled ortion 22 so arranged as to deflect the material which is beingcut.

The device thus constructed is adapted to be applied to the cutter 10 byinserting the member 10 between the members 12 and 15, through the endof the members adjacent the pivot 16, as shown in Figures 1 and 4, sothat the member 12 will engage over the top edge of the cutter 10 andthe shoe like portion 15 will engage over the cutting edge of thecutter.

The parts may be secured to the cutter in any desired or ksuitablemanner but preferably by means of fastening screws or bolts 23 whichpass through the walls of the member 12 and over the upper edge of thecutter 10 and are tightened so as to cause the member 12 to grip theupper edge of the cutter 10. The cutting edge of the cutter will thenenter the shoe like portion 15` and also between the upstanding portions21 of the member 15. rlhe cutter blade 10 will also pass between thedependingv jaws 20 of the. member 12 as shown more clearly in Figure 4.

ldith the parts thus arranged the jaws 2() will co-operate with thecutter 10 for holding the shoe like member 15 yieldingly in position,and to that end one of the upstanding portions 21 of the shoe likemember 15 will pass between the cutter blade 10 and the adjacent jaw 20.If desired each of the jaws 20 may be provided with an odset portion` orrecess 24 adapted to receive a pro.- jection 25 on the respectiveportions 21.

lVhen the parts are applied to the cutter as shown in the full lineposition in Figure 1, the extremity 18 of the shoe like member 15 willbe directed away from the cutting edge of the cutter 10 and willpreferably terminate adjacent the forward edge of the cutter so that inuse the shoe like member 15 will be directed under the material to becut, and this will raise the material as the cutter is advanced to causethe material to slide up the inclined surface of the portion 18 and willdirect the material between the shoe like member and the cutting edge ofthe cutter and press the material against the latter, to be severed. Thedeflector 19 is so arranged that it will stand in close proximity to thecutting edge so that any paste or foreign matter which is carried by thematerial into the forward end of the shoe like member 15 will bedischarged through the opening 17.

With this improved construction it will be manifest that the materialmay be cut while the same is applied to the wall with out danger ofmarring the wall and also withoutdanger of dulling the cutting edge ofthe cutter by reason of its coming into contact with the wall surface.The shoe like member will elevate the material to be cut and will alsohold the cutting edge out of contact with the wall.

When it is desired to gain access to the cutting edge of the cutter forsharpening or for other purposes, the shoe like member 15 may be movedabout its pivot 16 into the dotted line position shown in Figure 1,thereby permitting the edge of the cutter to be sharpened withoutnecessitating the removal of the attachment from the cutter.

While the preferred form of the invention has been herein shown anddescribed, it is to be understood that various changes may be made inthe details of construction and in the combination and arrangement ofthe several parts, within the scope of the claims, without departingfrom the spirit of this invention.
